' This intention" relates to a new aindimproved 'device for-separatingdirt and fore-ign,substanccfix-oni` ,cot-ton, and is" more, especiallydesigned for separating such substances from l long-staple cotton, `andwithout injuring the"iibre, but drawing it out, so that the gin 'mayoperate cifectually upon it withoutcutting or breaking it. The inventionconsists of a series of revolving toothed or armed cylinders placedwithin a case'or box, the bottom of which is provided with a series ofperforated concares, one underneath each cylinder. The cotton `is fedVinto one end of thecase or box, and the toothed or armed cylinders arel `rotated all in the same direction, and the cotton', by the action ofthe teethV or arms, passed or fed throughlthe esse or box, the libreduring this opera-.tion being drawn out and straightened, andthedirtandforeign `substances detached, dropping by their own gravitythrough the perforated concaves.

, A- represents 'a ease or box, which may be of any suitable d'mensions,the top .part bem'g arranged so` as te be capable of being lifted o toexpose or render accessible, when desired, the mechanism' `within it.`Within this case or box, A., there is litted transversely a series ofcylinders, B Bf B B", provided.` each with a seres fadialtecth or arms,arranged circumferentially in rows, as shown in iig. 2. These cylindersgradually` increase in-diameter from the -feed to the discharge end ofthe case or box, B being `the smallest, Bf rather Ilarger than B, andB'y'rratler'larger 'than 'B' the teeth or arms a 'of the severalcylinders increasing `in length corresponding with the increasedydiameter of the cylinders. (See iig. 1.) The bottom of the case orhormis"` t d of a series of conozntves,l C, one beingunderneath eachtoothed or armed cylinder.` These concaves 'is compose areconstructed'ofsheet metal, and perforatediwith halfinch `holes, baatsuitable distances apart to let outlthe cotton seed,'or admit of itsdischarge from the caseor box. The journals at one ond of the cylindersextend` through the side ofthe case or box, and have pulleys, c, uponthem, around which. belts pass,`all of thebelts` passing around andbeing driven from'the pulley ot'- the smallest. cylinder B, or, ifpreferable4 or` desired, motion e maybe communicated from fonecylinderto the-ciber by meals of gearing; but' whether `belts -cirgearing `are -used for this purpose, the arrangement must be suchas tohave thecylinders increase in speed aboutin proportion-astlrey increaseinzej Atene-end l of the case or-box'A. there is a hopper D, in whichthe cotton to be e operated upon is placed,.thc cotton passing from thishopper dowri'throughnn opening, d, into the case' or box A, directlyover the front part of `theslnall cylinder B. :The cotton is carriedaro'und the teeth or arms of@ the cyl-indeiin the direction indicatedbythe arrow, theteeth or armsrof one cylinder taking it frein the teeth orarmsf the other; By thislmeans the cotton is carried through the case orboar, and by that operation 'i This invention has been practicallytested,=and has been found to operate well, separating the sedrfromeleast' e l Havingthus described my invention, I. claim as new, anddesire to secure by Letters Patenttom composed of, 'a series ofperforatedconcave -the discharge end o the case or box, andtheir speedof rotation increasing aboutin` proportion to the increase of theirdimensions, substantially as and for the purpose set forth. i. e e e e ea The above speciiicationof my invention signed by ine this lithvday ofApril, 186fi.`
